12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service San Francisco Bay Area 1037 AM PDT Sun Mar 29 2020
SYNOPSIS. Scattered rain showers will spread inland through midday as a frontal boundary moves across the region. Dry conditions will develop tonight and persist through much of next week, aside from light rain potentially over the North Bay on Monday. Below average temperatures will continue and begin a slow warming trend by midweek.
DISCUSSION. as of 9:09 AM PDT Sunday . Forecast remains on track this morning. Visible satellite shows spin of clouds just offshore as upper low and surface boundary get ready to pass through the Bay Area. Radar showing scattered showers over land with heavier showers offshore getting ready to move inland from late morning through early this afternoon. Freezing levels around 5000 feet and small hail possible with heavier showers. Precip will end by this evening with dry weather overnight though valley fog formation is likely given recent rains, high boundary layer RH and light winds expected.
Another weak front approaches NorCal by early Monday and 12z NAM is holding onto light rain chances for coastal and northern Sonoma county, even into northern Napa on Monday. No significant rainfall expected up there but forecast will account for continued precip chances for that part of the district while everyone else dries out.
Long range models now show a more zonal/progressive/nw type flow for the upcoming work week. That results in dry weather and temps near normal with perhaps some slight warming later in the week. Generally looking for daytime highs mid 60s to mid 70s. Some upper 30s still possible for the coldest interior valleys but not expecting any frost potential for crop impacts this week.
Longer range trends suggest renewed rain chances by later next weekend into the week of April 6th with the long range cfs model implying above normal precip from mid to late April.
PREV DISCUSSION. as of 03:04 AM PDT Sunday . A mid/upper level trough approaching the region will result in an increase in rain showers through midday as a frontal boundary sweeps inland. These showers will likely produce anywhere from 0.10" to 0.25" with locally greater totals of around 0.50" within heavier rain showers. Precipitation will tapper off from northwest to southeast this afternoon as the boundary pushes inland and will likely end region-wide by late this evening. Meanwhile, temperatures will remain below seasonal averages with daytime highs topping out in the upper 50s to lower 60s.
Another weather system pushing inland to the north will allow for light precipitation over northern California and as far south as the North Bay on Monday. However, most locations south of the Golden Gate will remain dry and see the start of a gradual warming trend. The warming trend will continue region-wide through at least midweek as high pressure builds in from the Pacific and the storm track remains well to the north.
The latest operational forecast guidance and ensemble members are keeping temperatures near to slightly below seasonal averages through the remainder of the week. This is as the ridge of high pressure does not appear to strengthen as much as previously thought with broad troughing over the West. However, dry conditions are likely to continue across our region through at least late week.
Beyond the current 7 day forecast period, the ensemble mean from both the ECMWF and GFS suggest wet and unsettled weather conditions will return the week of April 6th. This will likely be accompanied by cooler than average temperatures as well as weather systems drop southward down the West Coast. This is also reflected in the Climate Prediction Center's 8-14 Day Outlook with higher probability of above normal precipitation across much of California.
AVIATION. as of 10:37 AM PDT Sunday . For 18Z TAFs. Scattered showers will continue to impact the terminals into the early afternoon. At that time, showers will become more isolated. Borderline MVFR/VFR conditions this morning with cigs lifting around mid-day and VFR conditions returning this afternoon. Models do show an increase in low level moisture this evening and overnight. MVFR conditions may return for some locations overnight with possible patchy fog in the North Bay early tomorrow morning. SE winds this morning generally under 10 kt, though at times winds may reach or exceed 10 kt. Guidance has delayed the wind shift out of the SW, therefore have pushed that back in the tafs by a couple of hours. Will monitor observations and make adjustments as needed.
Vicinity of KSFO . MVFR/VFR conditions this morning with rain showers bringing low ceilings. Shower activity will decrease in the afternoon though isolated precip will remain possible. Cigs expected to lift this afternoon, though FEW to SCT lower clouds may persist. E/SE winds this morning becoming W/SW this afternoon.
SFO Bridge Approach . Similar to KSFO.
Monterey Bay Terminals . MVFR/VFR ceilings this morning and early afternoon with scattered showers. Isolated showers then possible into this evening. Cigs expected to lift in the afternoon before MVFR conditions possibly return this evening and overnight. Light east to southeast winds this morning will become southwest to west this afternoon.
MARINE. as of 08:51 AM PDT Sunday . Generally light winds will persist across the coastal waters into early next week as high pressure shifts into the southern California waters. Northwest winds will increase mid week as an upper ridge builds over the eastern Pacific and an upper low moves inland well north of California. Mixed swell will continue with a moderate northwest swell and a light southwesterly swell.
